Message

At Questrade, I completed a database migration and conversion from SQL Server 2005 to Sybase 15 on Red Hat Linux. I also developed stored procedures, functions, triggers, and Bash scripts for database development and administration.

My work has included SQL Server, Oracle, and Sybase administration and development, with a focus on database design, performance tuning, and migration. At Medisolve Inc., I developed patient screening software with MS Visual FoxPro 8 for touch-screen kiosks.
